MOLD FOR SHAPING ICE.

SPECIFICATION lforming part of Lettexjslatent No. 678,017, dated July 9, 1901.

`Applicant' inea July 27, 190e.

To all whom t may concern:

l Be it 'known that We, HARRY A. MACCLY- MENT, of Hammond, Lakecounty, Indiana,y and WILLIAM F. SIMS, of Chicago, inthe 5, county of Cook and State of Illinois, have invented certain new and useful Improvements in Molds for Shaping Ice; and we do hereby i "edeclare that the following is a full, clear, and

exact description thereof, reference being had Io to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in ice-molds of that class whereby irregular I pieces of ice are formed -into symmetrical shape for use in iced beverages or on the table.

The invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims. l

In the drawings, Figure Alis a plan view of an ice-mold embodying theimprovements hereinafter set forth. Fig. 2 is aside elevation ofthe mold. Fig.3is an end elevation. Fig.4isaview in longitudinal secton,partially broken away, 2 5 showing the two parts of the mold in engagement. Fig. 5 is a vertical section on line 5 5 of Fig. 4, looking toward the center of the device. Fig. 6 is a vertical section on line 6 6 of Fig. 4, looking toward the outer end of the 3o half-mold. Fig. 7 is a horizontal section on line 7 7 of Fig. 4, showing the face andrdis-A charge-pipes. Fig. 8 is a view, partially in ivertical section, of another lform of the device. Fig. 9 is a section showing a detachable mold-face.

The device, in general terms, comprises a two-part mold provided with means whereby one or both of said parts .may be heated.. Suitable connections may be provided, if de-l sired, between thel two parts whereby they can easily be broughtinto accurate engagement, thereby closing the mold. The mold is preferably of a size that will make pieces that can be readily insertedin tu'mblers or glassesgbut any decorative designs for the table may be used.

A preferable form of mold which embodies the invention consists of a frame to which one of the mold parts is secured and on which the other of said parts has sliding'connection, whereby it may be made to close on said Xed Serial No. 24,978. (No model.)

are also provided in the mold. The sliding `co'nnection'may take the form of guide'rod or rods parallel to the frame on which the movable part of the mold slides and in alinement with the fixed part, or the guide rod or rods may be perpendicular to the frame.-V In this instance the frame acts as a base, on which the Xed part of the mold is secured,

the guide rod or rods in this case being a vertical standard or standards, on which the movable part of the mold slides in vertical alinemeut with the fixed part. A convenient 4means for heating either or both partsconsists in causing hot Water to circulate through pipes or chambers across the rear of the face of the mold in contact therewith. Another means which is desirable is to electrically heat metal-conductors which are in contact with the rear of the mold-face. Obviously a current of hot air or a gas jet or flame in lcontact with the mold may be used, and we do not restrict themselves to any particular form of Inold or device for heating same eX- cept as set forth in specific claims.

Referring to the drawings, A in Figs. l, 2, 3,' 4, 5, 6, and 7 represents a half-mold or part ofa mold of a horizontal type, which embodies the vessential features of the invention. lSaidxhalf-rnold contains 'a hollow chamber a5,

formed by a cylindric side wall a', an end wall a2, and the mold-face a3. The edge a4 of lthe mold-faceis preferably sharp, as shown.

Within the chamber a5 and close to the edge 0.4 is a tubular ring D, whose external diameter is slightly less than the internal diameter of the chamber. Said tubular ring is providedwith orifices d, which open or point directly toward the said mold-face d3 and the rear faces of the portion of the walls which form the cutting edge. Said ring is connected with a'feed-pipe d', which leads to any convenient hot-water supply. Eis an efflux-pipe tocarry the water from the chamber. The

standard B is shown 'as provided with two arms b, extending horizontally from opposite sides thereof. At the opposite end of the frame C a standard B', with arms h', similarly disposed, is suitably secured. Horizontal rods b2, parallel to the longitudinal axis of the half-mold A, connect the corresponding outer ends of said rods b and arms b and form guides on which a movable part of the mold A', similar in size and form to the fixed part A, has sliding connections, said two parts A and A being in axial alinement. Said sliding connection comprises the yoke-pieces F, which encircle the part A and have guideapertures through which the guide-rods b2` pass. It' it is desired to heat the movable part, a tubular apertured ring G, connected by the pipe g to a flexible tube g', may be used, g2 representing a exible efflux-pipe.

The parts of the mold may be ot' any suitable material, preferably of copper on account ot its high heat conductivity. The mold-face a3 of each part is shown as a concave hemisphere. This, obviously, may be of any desired form and the material may be anything suitable, such as porcelain. While the mold-face, so far as described, is xed in the mold part, it may be made removable therefrom, so as to readily and quickly change the design of the mold. A convenient form of such a device is shown in Fig. 9, wherein the mold-face, herein shown as conical, has engagement byinterior screw-threads a@ with the wall a of the mold, which permits of quick replacing of said face. In Fig. 9 there is also shown another form of hot-water-feed pipe G, which discharges against the upper part of the mold-face near its edge.

In Fig. 8 a vertical type of mold embodying the invention is illustrated. In this form of device the fixed part A of the mold is se-` cured directly to the frame C, while the movable part A is suitably secured in vertical alinement over said fixed part by a yoke F, which has sliding connection with a guide.

Said guide is secured to said frame C parallel i to the axis of the mold. A set-screw I may be used to clamp the part A in any position desired. Another form of heating device which may be used is also illustrated in Fig. 8. An electrical conductor K from Va suitable generating source leads through a control- The parts are separated, a piece of ice insert` ed, and the mold is closed thereon, the heating of the faces and applied pressure shaping the ice into the desired design. The use of sharpened engaging edges and the heatingV thereof to ahigher temperature than the moldl large pieces of ice and mold them to the size and design required.

We claim as our inventionl. A mold for shaping ice, comprising two' separable parts having recessed mold-faces and engaging edges 'and means for heating said edges.

2. A mold for shaping ice, comprising two parts having recessed mold-faces, and means for heating said parts, and connections be4- tween said parts for opening and closing the mold.

3. A mold for shaping ice, comprising two parts, either or each of said parts having a hollow chamber adjacent to the mold-tace, and means Within said chamber for heating said mold-face.

4. A mold for shaping ice, comprising two parts having engaging edges, either or each ot' said parts having a hollow chamber adjacent to said edges, and means within said chamber for heating said edges.

5. A mold for shaping ice, comprising two parts, either or each of said parts having a hollow chamber adjacent to the mold-face, and means for circulating hot water through said chamber.

6. A mold for shaping ice, comprising two parts, either or each of said parts having a hollow chamber adjacent to the mold-face, a

f hot-water-feed pipe in said chamber discharging against the wall adjacent to said moldface, and an etiiux-pipe from said chamber. 7. A mold for shaping ice, comprising two parts having engaging edges, either or each of said parts having a hollow chamber adjafv cent to the mold-face and said edges, a hot water-'feed pipe in said chamber discharging against the walls adjacent to said edges, and an efflux-pipe leading from said chambers.

8. A mold for shaping ice, comprising two parts each having a die-face detachably secured therein, and means for heating the dieface. l 9. A mold for shaping ice, comprising a frame, a part mold secured to said frame, a `part mold having movable connections with said frame whereby said mold may be closed,

IOO

.and means for heating one or both ot' said 4part molds.

In testimony that we claim the foregoing as our invention we atix our signatures, in presence of two witnesses, this 24th day of July, A. D. 1900. HARRY A. MACCLYMENT.
